AR-15s are popular because there’s a single standard, and all the parts made should fit that standard, and more-or-less work. I can buy a barrel from any one of ten or more manufacturers, and I know that it’s going to fit on my receiver (although I might need a different gas tube). You can’t do that with a Ruger Mini-14, you definitely can’t do it with any of the fuck-knows-how-many AK variants. ARs do have their own shortcomings it’s true, but all rifles have shortcomings; the AR-15 platform does a pretty good job of balancing the competing needs and desires.

True, but primarily, because NATO wants them in a certain spec.
Again, once the US military switche from it, then so will everyone’s opinion.
